A method for actuating a valve with an electromagnetic valve drive through which electric current is conducted to open or close the valve or to hold the valve in an open or closed position includes receiving an opening signal, determining an adapted opening signal which is adapted to physical limits of the valve or valve drive, and determining a feed-forward signal for feed-forward control of an electric current to drive the electromagnetic valve drive to open the valve in reaction to the adapted opening signal. The method further includes calculating an actuation signal for actuating the valve drive using the feed-forward signal, and outputting the actuation signal.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The method as claimed in claim 3, wherein the valve model models a first-order delay behavior of the valve.
5. The method as claimed in claim 3, wherein a time constant of the valve model corresponds to a time constant of the electromagnetic valve drive.
6. The method as claimed in claim 3, wherein an electric resistance of the electromagnetic valve drive is estimated in the valve model.
7. The method as claimed in claim 3, wherein an inductance of the electromagnetic valve drive is estimated in the valve model.
8. The method as claimed in claim 1, wherein a pilot control and a regulator are used to calculate the actuation signal.
11. The method as claimed in claim 1, wherein a control unit for actuating the valve is configured to carry out the method.
